GULF SHORES, ALABAMA — Day two of the Hangout Festival kicked off much like day one — with beautiful blue skies, white-sand beaches and a bill loaded with can't miss sets.

But what happened in the 12 hours that followed after gates opened at 11 a.m. on Saturday was unlike anything this town (or this festival) had seen before: an MTV star and a supermodel engaging in a "Selfie Challenge," an up-and-coming EDM star patrolling the beaches in a suit, and plenty of big-time sets from big-time talent, of both the new and established variety.

There was the hit-packed, free-wheeling set from the night's headliners, Tom Petty and the Heartbreakers, full of tried-and-true fist-pumpers and expansive, expressive jams, to the cooly-confident effort from Kendrick Lamar, who packed 'em in at the Hangout's Boom Boom tent, despite the fact he didn't make his set time. Bassnectar was true to his name, delivering with gut-massaging low end, Public Enemy were just as furious as always, the Roots killed in the afternoon sun, and DFA upstarts Holy Ghost made the most out of their early-evening stage with moody, Disco-tinged pop.

And, hey, the weather was amazing, too ... yet another fantastic day at the Hangout. And with a Sunday bill featuring Stevie Wonder, Trey Anastasio, Imagine Dragons, Ellie Goulding and many more — plus plenty more from our team in the field — things are only getting better. We could get used to this.
